How many people your age in the US will live to 80?
Will you be one of them?
“How much time do I have?” — a thought most of us push away. Take the test and replace the worry with numbers: your chance of living to 70, 80 and 90, your Health Age and your biggest risks — based on actuarial tables and studies of millions of people.

Worry doesn't count. Statistics do.
The test has three steps. We start from the average chance for people your age, shift it with your answers — and show the result next to your own guess.
1
Your starting point: your age and sex
An actuarial table shows how many people of your sex and age reach each next birthday. That's your starting line.

How your forecast is calculated.
We start from the official actuarial table for your sex and age, adjusted for your country. Then each of 21 factors shifts the risk as much as meta-analyses of hundreds of thousands to millions of people show.
Statistical estimate, not medical advice or a diagnosis. If something worries you, talk to a doctor.
- Base
- Social Security Administration period life table, 2023, adjusted for your country
- 21 factors
- Smoking, alcohol, fruits & vegetables, sugary drinks, exercise, steps, sitting, BMI, sleep, stress, outlook, diagnoses, blood pressure, checkups, self-rated health, father, mother, family history, income, partner, close friends
- Overlapping factors
- We damp related factors so nothing counts twice — weight and blood pressure, for example
- Disease risks
- Average lifetime risk from large studies, adjusted for your factors; causes of death from CDC, NCHS — 3M deaths in 2024
- Sources
- CDC, Social Security Administration, NEJM, The Lancet, JAMA Internal Medicine, Circulation, Nature Medicine, Sleep, Genetics

Questions before the test.
How much does it cost?+
Taking the test is free. Your full result and Longevity Card cost $2.99 and include 7 days of MyTestPro Full Access — every test on the site. After that it's $19.99/month; cancel anytime in your account. You see the price before you pay.
How do you know my country?+
From where you open the page. The country adjusts the actuarial table. If it's wrong, change it at the top of the page or in the test.
Is this a medical diagnosis?+
No. It's a statistical estimate: how often people with the same age, sex, habits and health reach a given age and get sick. It doesn't replace a doctor's visit.
Won't it be scary?+
We show your risks and what already works in your favor — most people have both. Next to every risk you see the average for your peers, so you can see the scale.
How accurate is it?+
The forecast stands on an official actuarial table and meta-analyses covering more than 23.6 million people. It's a probability for people with your profile, not a prediction of your future.
Who sees my answers?+
Only you. We don't ask for your last name or medical records. Your Longevity Card is public only if you share it.
Find out your chance of living to 80.
